• Easily incorporated in the SQL database engine without any single server system
• Reads and write data to ordinary disk files that allows you to recover data from backup to maintain business continuity

SQLite database gets corrupt for various reasons, such as application crash, power failure during a transaction, or an operating system crash. However, the most prominent reasons behind its corruption include:

• When one of the files get overwritten by a rogue thread or process
• Using a file descriptor continuously even after closing it
• Swapping journal files between two different databases, overwriting a journal file, or moving a journal file without copying the journal
• Having broken or missing lock implementations in the filesystems
• Using different locking protocols that might be inappropriate for file systems
• Due to disk drive and flash memory failure
